Title: Heat sink excellent in heat dissipation characteristics
Inventor: TASAKA MASAHIRA
IPC: H01L23/467
Filed: 1995-05-24
Abstract: PURPOSE: To increase the heat dissipation area without increasing the size of heat sink, the pressure drop of working liquid for cooling or the occupation area by employing a hollow protruding heat dissipation body having porous circumferential wall and passing a cooling fluid through the pores thereby removing the heat therefrom. CONSTITUTION: Heat generated from a heating element, i.e., a chip, passes through the bottom plate 32 of a heat sink and transmitted by thermal conduction to the solid part of a heat dissipation tube 34. Cooling air fed through an air supply port 43 is fed through each opening 42 in the center of a top plate into the hollow region 33 of heat dissipation tube and then passes through a channel comprising countless holes in the heat dissipation tube while removing heat from the solid state thereof. The warmed air passes through the unprotruding part 44 around the heat dissipation tube 34 and sucked through a suction port 45 and collected. This structure makes uniform and enhances the cooling efficiency of porous heat dissipation body.

Title: Injection member for die casting machine and manufacture thereof
Inventor: KAWAGUCHI NAOTAKA
IPC: C23C16/36
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain excellent heat resistance and erosion resistance by forming a surface reforming layer consisting of a specific metallic compound on the surface of an injection member in direct contact with molten metal. SOLUTION: Basic material is made of iron alloy based heat insulating material containing, by wt.%, 8-15% Ni, 5-9% Si, 1.0-1.5% C, and on this surface, the surface reforming layer consisting essentially of at least one kind selected among carbide, nitride, boride and oxide of 4A group, 5A group and 6A group metals in Periodic Table is formed by a CVD method. The most desirable surface refining layer is multi-laminated layer containing layers consisting essentially of TiC and TiN and a layer consisting essentially of TiCN between the layers. The surface reforming layer delays the heat diffusion to the base material and restrains the solidification of molten metal. Further, since the generating energy of the reforming layer is high to hardly cause decomposition, the heat resistance and the erosion resistance are improved.

Members 2, 3 are welded each other by using an appropriate welding process such as the arc welding process by fusing them gradually from the outer face of the cylinder 2 toward the side member 3 while holding these component parts 2, 3 turning in the direction of the arrow B. Thus a firm solidification is obtained with the welds D having an approx. triangle profile. Then thermomedium such as water, SK-oil etc. is poured in from an opening 6 formed at an appropriate location in the roller's body 1 and sealed by applying an appropriate method and after releasing the air in the roller's body 1 through the opening 6 the opening shall be closed tightly. By this procedure an enhancement of welding qualities can be assured.

Abstract: PURPOSE:To prevent the oscillation phenomenon of the waveform equalizing system by a malfunction by constituting the system so that the fetched reproduced brightness reference signal and reproduced color reference signal may detect the distortions received at the time of the transmission and the synchronization of the both reproduced signals may be applied. CONSTITUTION:A reference signal insertion means inserts the brightness reference signal and the color reference signal into the brightness signal and color signal of the video signal to be transmitted and transmits them to the processing system on the side of the transmission. At the waveform equalizing means, the brightness signal transmitted via the processing means on the side of the reception is inputted at a reproduced brightness signal transmission characteristic compensation circuit 8A, the color signal is fetched at a reproduced color signal transmission characteristic compensation circuit 8B, respectively and these both fetched reproduced signals detects the distortions received at the time of the transmission at CPU 10, respectively. At the synchronizing means (timing circuit), the synchronizing deviation of the both reference signals is eliminated. Transversal filters 13, 20 cancel the respective transmission distortion portion detected from the transmitted brightness signal and color signal. Thus, the transmission characteristic compensations in the both transmission systems can be performed by the feed forward control.
